Front Panel Features
At the back of the manual, you'll find fold-out diagrams of the front and rear panels.
As you're reading the descriptions of the preamp's features, you'll gain a better
understanding of the topic of discussion if you unfold and refer to them as we go!
This option comes in handy when you want to insert another preamp or an effect
processor into a serial loop along with the ENGL Preamp 570. If the other preamp can
also be bypassed, you can switch between the two preamps on the fly or even run
them both at the same time. If you want to connect a second preamp, insert it into the
stereo effects loop and set the Preamp Defeat status and FX Loop status active when
you want activate the second preamp. You could even daisy chain several preamps or
effect processors.
Clean channel Gain control. This knob determines the preamp's input sensitivity in
Clean mode; use it to set the desired input level.
The amount of distortion depends on your guitar's pickups and the Gain Boost (3)
setting. In Clean mode, single-coil pickups may begin saturating the preamp when the
knob is set to about the two o'clock position; pickups with very high output levels
(humbuckers or active pickups) will evoke mild overdrive at even lower settings. If you
want squeaky clean tone, simply back off the Gain knob accordingly.
Boosts the input sensitivity of Main Channel 1, and . The red LED above
this button lights up to indicate is on. can also be switched via
MIDI program change command or the Custom Z-9 Footswitch.
As its name would imply, serves primarily to up Clean and Crunch channel
input levels, extend both channels' gain ranges. In effect, this feature gives you two
additional variations on these two channels' basic sounds. For example, you could set
the Clean channel Gain knob to the highest setting at which your guitar signal remains
distortion-free, just under the preamp clipping threshold. Then when you activate
, you will overdrive the Clean preamp slightly, yielding a grittier tone well-
suited for rock riffs.
Another Clean channel option is to use the as a volume booster. To do this,
activate and dial in a Clean Gain knob setting, making sure not to push the
preamp into clipping zone. Consider this your high-volume clean tone, say for clucking
lead lines. Switching off gives you a softer clean tone for chord work.
Switch back and forth between the two as desired.

This is a bypass that cuts the preamp out of the signal chain when you press the button.
In this case, the input signal is routed directly to the Send jack. The LED located above
the button illuminates to indicate the preamp is bypassed.
